IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent N o. 199,072, dated January8, 1878; application filed rFebruary 9, 1877.

Fig. 4 is a perspective view of the reciprocating molds and plungersused in the machine.

My invention consists in combining, in a brick-machine, arectangular-shaped frame,

provided with three parallel divisions, in which are located acompression and two discharging plimgers, connected withI and receivingmotion from a triple crank-shaft; a transverse sliding mold-frame, withlever and grooved cam-wheel for operating the same; and an airvalve,which opens for the exit of air while the mold is filling, and closeswhen the clay is compressed.

The object of my invention is to provide a machine which will embodysimplicity in construction, be economicalin operation, and easilyrepaired or cleaned when occasions require.

Y The frame A of the machine, which is of a rectangular shape, isdivided, by the longitudinal partitions a a, into three divisions, asshown at Figs. 2 and 4. B, B1, and B2 are three plungers or pistons,located in said divisions at the front end of the machine, and supportedupon guides bolted to or formed on the sides and partitions of theframe. These plungers are arranged parallel, and are reciprocated from acrank-shaft, C, mounted transversely in bearings D and D at or near thecenter ofthe frame.

E, El, and E2 are cranks on the shaft C, and y F, F1, and F2 are forkedrods or levers, for connecting the plungers to the same. G, Figs. l and2, is a covering-plate, placed over the plungers and bolted to theframe, to shield the plungers and assist in maintainingthem in position.

The frame H, which is operated in conjunction with the three plungers B,B1, and B2, is constructed to form two brick-molds, I I, and is arrangedin guides J J, formed on or bolted to the front end of the machine, andreceives a transverse reciprocating movement from a lever, K, pivoted tothe frame and operated from a grooved cam-wheel, L, on the shaft C, asshown in Figs. 2 and 4.

The clayis compressed and the bricks formed by the central plunger B,immediately in front of which and on the outside of the mold-frame H isa platen, M, bolted securely to the end of the machine to receive thepressure of the molded clay, as shown in Figs. 1, 2, and 3. N is anair-valve, arranged in the center of the said platen and opening intothe brick-molds, for the exit of air while the clay is being forced intothe mold. The said valve is connected to a lever, O, which has itsfulcrum on the front end of the machine, and is provided with a spring'for retaining the valve open. The upper end of the lever 0 is connectedto a sliding rod, B, which is supported in a bearing on the top of theframe, and is forced outward to close the valve when the upright S, onthe plunger B1, is brought in contact with it.

The right and left plungers Bl and B2, which alternately discharge themolded bricks fromY the molds I I, are each made of greater length thanthe compression-plunger B, in order that the front end will be inadvance and project through one of the molds and discharge a nishedbrick while the center plimger is compressing the clay in the othermold. The clay is received from the pug-mill T into an open space, U, infront of the plunger B. This space holds sufficient clay to form onebrick at a time, the clay being cut off from the pug-mill by theadvancing plunger.

The grooves in the cam-wheelL are arranged to cross in a right and leftdirection, so as to shift the rear end of the lever K from one side tothe other, which movement carries the moldframe H, which is connected tothe front end of the lever by means of the vertical pin d, from side toside of the machine.

When the swivel at the rear end of the lever is traveling in thestraight portion of the groove on the right or left hand side of thecam, the mold-frame is at rest and the plunger B is compressing theclay, while the side plunger' B2 (for example) is discharging a finishedbrick. When the center plunger has nish ed compressing the clay and abrick is discharged from one mold, the frame is shifted by the cam andlever toward the opposite side of the machine until l J[he filled moldis directly opposite the di scharging-plunger B1 and the empty moldopposite the plunger B, in which position the operation of compressingand discharging a brick is repeated.

The vertical shaft Q of the pug-mill is provided with blades e e e,Ste., for mixing and tempering the clay, and with a screw, Y, at Jchelower end, for forcing the clay into the open space in front of thecompression-plunger. The said shaft is driven by means of a bevel-gearwheel, P, on the upper end, and a similar wheel, P', on a horizontalshaft, V.

An endless chain, X, passing over a chainpulley, Z, on the shaft C,andover a smaller pulley, Z', on the shaft V, communicates motion to thegearing and also to the vertical shaft. l

The shaft C is driven from a shaft, C', through a pinion, W, and aspur-Wheel, W.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, il

l. In combination with the molds I I, compression-plun ger B, and platenM, the air-valve N, lever O, rod R, and upright S operated by themovement of the plungers B and B2, substantially as herein shown anddescribed.

2. The combination, in a brick-machine, of the frame A, partitions a c,compression-plunger B, discharging-plungers B1 and B2, shaft C, cranksE, E, and E2, levers F, F1, and F2, movable mold-frame H, guides J J,platen M, grooved cam-wheel L, lever K, shaft C', pinion W, andspur-Wheel W', operating sub stanti ally as herein shown and described.
